MACHINE FOR RCUNDING HAT-BODIES.

SPECIFICATION forming part of Letters Patent No. 557,896, dated April'7, 1896.

Application filed August Z, 1895- To all 10700720 it 777/[LZ/ concern.-

Be it known that I, AUGUSTUS C. SAXTON, a citizen of the United States,residing at Bethel, in the county of Fairfield and State of Connecticut,have invented certain new and useful Improvements in Machines forRounding Hat-Bodies; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has for its object to produce a machine for roundinghat-bodies which shall be simple and inexpensive to build, will insure aperfectly neat and uniform quality of work, and which shall, moreover,have a capacity greatly in excess of any other machine heretofore builtfor this class of work. )Vith these ends in view I have devised thenovel machine of which the following description, in connection with theaccompanying drawings, is a specification, numbers being used todesignate the several parts.

Figure 1 is a plan view of the machine complete; Fig. 2, an elevationthereof; Fig. 3, an end view, the cone being removed; and Fig. i is adetail sectional view of the cutter and upper feed-roller.

1 denotes the frame of the machine, which may be of ordinary or anypreferred construction.

2 denotes a shaftsuitably journaled in the frame, to which power isapplied by a belt (not shown) running over a belt-pulley 3. At the innerend of this shaft is a roller 4, which Iterm the lower feed-roller andwhich also serves as the lower cutting-roller.

5 denotes a shaft one end of which is jour naled in the frame in such amanner as to rocki. 8., to permit a slight upward and downward movementof the opposite end of the shaft for the purpose of adjustment, (seedotted lines, Fig. 2,) said opposite end being journaled in a sleeve 6,having a threaded shank 7, which is adjustably secured in the frameworkby upper and lower adjusting nuts 8. Near the inner end of shaft 5 is acutter 9, the edge of which laps past the edge of roller 4, on the innerside, as clearly shown in Fig. 3.

10 denotes the upper feed-roller, which is provided with a centralopening 11, through Serial No. 560,432. (No model.)

which the shaft passes loosely, the inner face of the roller lying incontact with the face of the cutter, as clearly shown in Fig. 4. Theouter end of the shaft is threaded and the cutter is turned up tightagainst a shoulder 12. Roller 10 is held in position by a washer 13,against which a spring 14 bears, the tension of said spring beingadjustable by means of a socket-nut l5,which engages the threaded end ofthe shaft and receives and holds the spring securely. (See Fig. 4.) Thecutter is held closely in contact with roller 4 by means of a spring 16,one end of which presses against a collar 17 on shaft 5, the other endbearing against the framework, the action of said spring being to forcethe shaft toward the left. Motion is communicated from one shaft to theother by means of a gear-wheel 18 on shaft 2, which engages acorresponding gear-wheel 19 on shaft 5.

The hat-body to be operated upon is carried by a cone 20, having a shortshaft 21, which engages a socket 22 in a carriage 23. The cone ispreferably journaled at such an angle to the frame as to place the upperside thereof in line with the engaging surfaces of the feed-rollers, asis clearly shown in Fig. 2. The carriage is adjusted in or outrelatively to the cutter to regulate the length of the rounded bodies bymeans of pinion 24, (see dotted lines, Fig. 2,) which engages a rack 25on the carriage, and whose shaft 26 is provided with a hand-wheel 27 forconvenience in operation. This hand-wheel is provided on its face with ascale 28, which corresponds with a scale 29 on a plate 30, which issecured to the carriage and moves in a guide 31 on the frame. Thehand-wheel is locked in position at suitable adjustmentsfor instance, atadjustments of one-fourth of an inch-by means of a spring-bolt 32, whichis socketed in an extension from the frame and is adapted to engagerecess 33 in the hand-wheel. (See dotted lines, Fig. 2, also Fig. 3.) Itwill be seen that the adjustment is very convenient and practicallyinstantaneous in changing from one length of hat-body to another, eitherof the scales showing at all times to just what length the bodies arebeing rounded or trimmed.

It will of course be understood that the special design of the frameworkand of the carriage is not of the essence of my invention. I preferably,however, design and organize the machine substantially as shown in thedrawings. It is of course necessary that the carriage be provided with arack orits equivalent and that the parts be so constructed that thecarriage will move easily in the framework, but without lost motion. Itherefore form the rack upon a bar 34, which slides in a correspondingsocket in the frame, and also support the carriage at the top by meansof a plate 30 and guide 31.

The reason my present machine will do better work and more work thanother machines heretofore used for this purpose is owing to the factthat the feed is such that the work is self-holding-that is to say, thehatbodies are acted upon by the feed-rollers in such a manner that theyare drawn toward the cutter until after the cut is made, all tendency ofthe hat-body to run out being avoided, and instead of a tendency to runout the hat-body is drawn inward toward the cutter. In order toaccomplish this result, I journal the cone obliquely to the verticalplane of the machine and inclining in the direction from which thehat-body is fed, (see Figs. 1 and 3,) and also journal said coneobliquely to the horizontal plane of the machine-that is, oblique to thecentral line of the machine,as viewedin the horizontal plane, andinclining upward. (See Fig. 2.) The effect of this arrangement of thecone relatively to the cutters will be clearly understood from Fig. 1.It will be apparent that just as soon as the edge of the hat-body isplaced between the feed-rollers the action of said rollers will be todraw the edge of the hat-body inward toward the cutter, which actioncontinues until after the edge has passed the point at which the cuttingaction takes place.

The feeding action is as follows: It will be noticed (see Figs. 3 and 4)that the feed-rollers and the cutter are of equal diameter, and,furthermore, that the distance between the centers of the shafts is lessthan the diameters of either of said rollers or the cutter. It will alsobe noticed that the cutter laps past the lower feed-roller and that theupper feedroller, which is in peripheral engagement with the lowerfeed-roller, is provided with an enlarged central opening, through whichthe shaft passes loosely. The result of this construction is that in usethe upper feed-roller is carried forward by the lower rolleras far asthe central opening will permit, (see Fig. 3,) so that the hold of therollers upon the hatbody is forward of the point at which the cuttingaction takes place. This insures a perfectly-even feed and renders itimpossible for the hat-body to buckle or double in the machine.

Having thus described my invention, I claim 1. In a machine of thecharacter described, the combination with suitable feed-rollers and acutter, of a carriage, and a cone journaled in the frame obliquely.

2. I11 a machine for rounding hat-bodies the combination with suitablefeed-rollers and a cutter, of a cone journaled in the frame obliquely tothe vertical plane of the machine and inclining in the direct-ion fromwhich the hat-body is fed, and obliquely to the horizontal plane of themachine and inclining upward so that in use the hat-body is drawn towardthe cutter, and tendency to run out is avoided.

In a machine of the character described the combination with a conejournaled in the frame obliquely both to the vertical and the horizontalplanes of the machine, of shaft 2 carrying the lower feed-roller 4,shaft 5 carrying a cutter which laps past the edge of feedroller it,upper feed-roller 10 having a central opening through which shaft 5passes loosely,

a washer, spring and socket-nut by which the disk is held in operativeposition and suitable means for imparting rotation to said shafts as andfor the purpose set forth.

4:. In a machine of the character described, the combination with thecone, of shaft 2 carrying lower feed-roller 1, and shaft 5 carryingupper feed-roller 10 and cutter 9, one end of said shaft being journaledin the frame and adapted to rock in the vertical plane, and the otherend being j ournaled in a sleeve having a threaded shank 6 which passesloosely through the frame and is adjustable by means of nuts 8 engagingthe opposite sides of ,the frame.

5. In a machine of the character described, the combination with thecone, of shaft 2 carrying lower feed-roller 4:, shaft 5 carrying acutter the face of which is adapted to bear against the side offeed-rollei land an adj ustable collar 17, upper feed-roller 10 having acentral opening through which shaft 5 passes loosely, suitable means forretaining the upper feed-roller in position and a spring 16 one end ofwhich bears against the frame the other against collar 17 whereby thecutter is retained in operative position.

6. The combination with feed-rollers and a cutter, of a suitable frame,a carriage-having a rack and a socket 22, a cone having a shank adaptedto engage the socket, shaft 26 carrying a pinion engaging the rack and ahandwheel 27 having a scale on its face to deter mine the adjustment ofthe cone relative to the cutter, and recesses 33, and a spring-bolt toengage the recesses to lock the carriage at any adjustment.

In testimony whereof I affix my signature in presence of two witnesses.

AUGUSTUS G. SAXTON.
